LOOSE LEAF BINDER Filed. Nov. 4, 1926 Patented Nov. 19, 1929 UNITEDSTATES CHESTER G. VAN BUREN, OF CHICAGO, ILLINOIS LOOSE-LEAF BINDERApplication filed November 4, 1926. Serial No. 146,110.

My invention relates to improvements in loose leaf binders and has forits object the provision of an improved construction of this characterwhereby loose leaves of paper or the like may be readily bound and heldtogether or released for rearrangement, replacements or the like.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in 1 which,

1 is a perspective view of a loose leaf binder embodying the invention;

Fig. 2 a section of the same;

Fig. 3 a sectional view taken substantially on line 33 of Fig. 1;

Fig. 4 a sectional view taken substantially on line H of Fig. 3.

The form of construction illustrated in Figs. 1 to 4c inclusivecomprises two angle 2 irons 9 and 10 associated together as shown andpivotally connected at one end by means of the pivot 11 to providebetween them a space for the reception of the edge of loose leaves ofpaper 12 or the like. The other ends of the angle irons 9 and 10 aredetachably connected with each other by means of a lip 13 form d on themember 9 adapted and arranged to engage an opening 14 formed in themember 10 and whereby the corresponding ends of said members aredetachably connected together. A curved leaf spring 15 is arranged inthe space between the members 9 and 10, being secured to the member 9 atone end by means of the rivet 16, the other end of said spring slidingfreely upon the other end of the member 9 and whereby a binding pressurewill be exerted by said spring upon the edges of the loose leaves 12inserted between the members 9 and 10. By this arrangement, it will beobserved that any desired quantity or number of leaves 12 may be readilyinserted between the members 9 and 10 and detachably bound therein. Whenit is desired to release said leaves, the corresponding ends of themembers 9 and 10 are sprung to remove the lip 13 from the opening 14,whereupon the spring 15 will force said members to spring apart. When itis desired to rebind the loose leaves 12, all that is necessary is toplace their edges in the space between the members 9 and 10 and forcesaid members together until the lip 13 engages the opening 1 1 to locksaid members in binding relation.

In order to protect the loose leaves thus bound, the binding elements 9and 10 are preferably mounted in suitable covers. To facilitate suchmounting, the horizontal leg 10 of the angle iron 9 is arranged within achannel-reenforcing member 17,. being then compressed upon the leg 10 toform the same into an enlarged base as shown. The enlarged base thusprovided is then bound and secured in the binding of the cover members18 as shown and whereby the said cover members will serve to protect theloose leaves 12 held between the binding members 9 and 10.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, donot wish to be limited to the precise detailsof construction set forth, but desire to avail myself of such variationsand modifications as come within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secureby Letters Patent isz 1. A binder comprising two angle members pivotallyconnected together at one end and detachably connected at their otherends to provide a rectangular shaped space for the reception of detachedleaves of paper or the like, said space formed on three sides by saidangle members and open on the remaining side; a leaf spring secured toone of said members to bear upon and bind leaves or the like in saidspace; and cover members connected with said angle members to protectleaves bound thereby, substantially as described.

2. A binder comprising two angle irons pivotally connected together atone end, the other ends of said angle irons being detachably engagedwith each other adapted to provide a rectangular shaped space for thereception of detached leaves of paper or the like, said space formed onthree sides by said angle irons, and open on the remaining side; and aleaf spring secured at one end to one of said angle irons, the other endof said spring being free, said spring being arranged and adapted tobear upon and bind leaves of paper or the like between said angle irons,substantially as described.

3. A binder comprising two angle irons pivotally connected together atone end, the other ends of said angle irons being detachably engagedwith each other adapted to provide a rectangular shaped space for thereception of detached leaves of paper or the like, said space formed onthree sides by said angle irons, and open on the remaining side; a leafspring secured at one end to one of said angle irons, the other end ofsaid spring being free, said spring being arranged and adapted to bearupon and bind leaves of paper or the like between said angle irons; anda cover member permanently secured to one of said angle irons,substantially as described.

4. A device of the class described comprising cover members hingedlyconnected together; a metallic channel member secured within and betweensaid cover members at the hinged connection thereof, and having aninturned longitudinal flange on each side thereof; and a detachableclamping member comprising two angle irons pivotally connected togetherat one end and deta-chably connected at the other ends to provide alientangular shaped space for the reception of leaves or the like, saidspace formed on three sides by said angle irons and open on the remaining side, and a leaf spring secured to one of said members to bearupon and bind leaves or the like in said space, said clamping memberbeing adapted for slidable connection with said channel member, and tobe retained therein by said flanges substantially as described.

In testimony whereof I have signed my name to this specification.
